Simply enter the following command at the terminal, then you can safely use the $ (ABCDE) variable in the makefile file, which has a value of BBBMakefileFun.h#include class Test {public: void static display(const char *str);};Fun.cpp#include "fun.h"void Test::display(const char *str) { std::cout Main.cpp#include "fun.h"int main() {#if defined AAA Test::dis
Recently in learning Linux under the C programming, bought a called "Linux environment in the C Programming Guide" read to makefile more and more confused, may be my understanding can not.
So Google came to the following article. Plain and easy to understand. Then post it for easy learning.
PostScript, read this article and the "Linux environment in the C Programming Guide," The makefile chapter of the asto
1 Background 1.1 Docker introductionDocker is a container engine project based on lightweight virtualization technology from Docker, the entire project is based on the go language and complies with the Apache 2.0 protocol. Today, Docker can quickly automate deployment of applications within the container, and can provide container resource isolation and security
Makefile and makefile
At first, I will intercept a piece of nonsense about how to learn makefile. If you don't want to listen, please jump directly to my makefile tutorial.
First of all, we must first explain that learning makefile is really a painful process, especially the
I. What is in Makefile?
Makefile mainly contains five things:Explicit rules,Concealed rules,Variable definition,File indicationAndNote.
1,Explicit rules: Explicit rules demonstrate how to generate one or more target files. This is clearly pointed out by Makefile writers that the files to be generated, the dependent files of the files, and the generated commands.
[LINUX Network Programming] Makefile and network programming makefile
Some Reading Notes in Chapter 2nd of Linux Network Programming (version 2)
Makefile: defines a series of rules in a project that contains a large number of files to specify the sequence of compiled files, which can be used to manage projects.

Docker installation and sharing of common commands and sharing of common docker commands
Basic commands
1. To install docker in yum, the root permission is required.
Yum install docker
2. Start docker
Systemctl start docker. servi
, because the other file's target source file already exists, so the compiler does not need to compile all the code to generate a new executable file, and only need to compile the changed source files, and then connect all the target files on it, which is very important in the large project development, This can reduce the compilation time from several hours to a few minutes. That's what make can do.Makefile Document Writing SpecificationThe Makefile

In the previous kernel compilation, we mentioned that driver compilation is dividedStatic CompilationAndDynamic CompilationStatic compilation is to directly compile the driver into the kernel, and dynamic compilation is to compile the driver into a module.

1 PrefaceSince its inception, Docker has led the technology boom in lightweight virtualization containers. In this trend, Google, IBM, Redhat and other industry leaders have joined the Docker camp. While Docker is still primarily based on the Linux platform, Microsoft has repeatedly announced support for Docker, from p

1. function call
$ (Function arguments) # $ the referenced result is the result generated by the function.
2. Common functions in Makefile
1) $ (wildcard PATTERN) # match the files in the current directory
For example, src = $ (wildcard *. c) # Matches all. c files
Tags: blog Io ar SP file on 2014 Take a set of simple. c files as an example. The learning process from compiling commands to makefile. The GCC parameters are not described too much.

By default, make will look for the makefile file to read and execute in the file name order in the working directory (the directory where the make is executed), looking for the file name in the following order: "Gnumakefile", "Makefile", "makefile".Usually you should use "makefile" or "
Lesson 3 make Makefile (I) and make makefilePreface:
The previous course explains the gcc compilation process to its practice. You can see that some of these steps can simplify compilation, however, due to the large number of parameters and the large number of files in the project, errors may occur, or even a lot of time is wasted on compilation. Therefore, this tool is also available in the linux system: makefile.Principle:
In fact, the essence of
Objective:You don't need to edit a slightly obscure makefile file when you build a C + + program using VS on Windows, and for starters, they don't even realize it's there. VS is to automatically generate makefile files and build the project. There is no denying that Visual Studio is an all-purpose IDE, it helps developers do a lot of work, but also reduce the threshold of the C + +, the significance is very

Makefile condition judgment ---------- [Badboy], makefile condition badboy
Conditional judgment allows make to select different execution branches based on different running conditions. A conditional expression can be used to compare the value of a variable or a constant.
I. Example
In the following example, determine whether the $ (CC) variable is "gcc". If yes, use the GNU function to compile the target.
